## Description

The WP Document Revisions plugin for WordPress is vulnerable to Sensitive Information Exposure via the REST API term endpoints for document taxonomies in all versions up to, and including, 5.8.1. This is due to term counts, as well as the hide_empty and orderby=count query options, being based on counts that include draft, pending and private documents. This makes it possible for unauthenticated attackers to determine how many non-public documents carry each workflow state or custom document taxonomy term, and which terms are used only by non-public documents.
